Apresenta-se um modelo matemático que avalia numericamente a estabilidade do estado estacionário para escoamentos água-ar em sistemas pipeline-riser de geometria variável. Uma análise a partir da teoria de estabilidade linear é aplicada a um modelo matemático adequado ao escoamento água-ar no sistema pipeline-riser. O modelo considera equações de continuidade para a fase líquida e para a fase gasosa, admite-se escoamento unidimensional e em condição isotérmica. O líquido é considerado incompressível enquanto que a fase gasosa é considerada um gás ideal. Admite-se uma equação de momento simplificada para mistura onde despreza-se a inércia (NPW - Modelo No Pressure Wave) e o padrão de escoamento local é definido com base nas condições do escoamento e na inclinação local. Assim, a intermitência severa é controlada principalmente pela gravidade no riser e pela compressibilidade do gás no pipeline. Tanto a correlação de fluxo de deriva quanto o cálculo da queda de pressão por atrito, adotados como lei de fechamento do modelo, são determinados em função do padrão de escoamento. Injeção de gás e válvula de choke são consideradas, respectivamente, na base e no topo do riser. O modelo é aplicado à sistemas pipeline-riser com escoamento água-ar citados na literatura. Os resultados da análise de estabilidade linear numérica são comparados aos resultados experimentais e numéricos apresentando uma excelente concordância. / A mathematical model that numerically evaluates the stability of the stationary state for hilly terrain air-water flows systems is presented. Numerical linear stability analysis is performed to a suitable mathematical model for the two-phase flows in a pipeline-riser system. The mathematical model considers the continuity equations for the liquid and gas phases, one-dimensional flow and isothermal conditions. The liquid is assumed incompressible while the gas phase is considered as an ideal gas. A simplified momentum equation for the mixture, neglecting inertia (NPW - No pressure wave model) is considered and the local flow pattern is defined based on the flow conditions and the local inclination. In this way, severe slugging is controlled mainly by gravity in the riser and compressibility in the pipeline. The void fraction and friction pressure drop, utilized as closure laws, are determined based on the local flow pattern. Gas injection at the bottom of the riser and a choke valve at the top are considered. The model is applied to air-water pipeline-riser systems reported in the literature. Numerical linear stability analysis results are compared with experimental and numerical results reported in the literature with excellent agreement.

Globally, Atlantic salmon aquaculture is faced with a critical challenge: How best to deliver long-term sustainable growth, whilst optimising the opportunity for the expansion of the industry presented by an increasing global seafood demand? The thesis presents a novel framework of complementary decision support approaches to enable decision-makers to better understand the factors influencing aquaculture development, and examine alternative production (growout) technologies that more effectively address the challenges associated with intensification and expansion. The framework was developed through a combination of fieldwork (international data-gathering), key stakeholder discussions, and the application of targeted qualitative and quantitative analytical approaches; using the Tasmanian industry as a Case Study. The initial research focused on shorter-term (tactical) decision support. A situational analysis defined the business environment, and appraised viable expansion options (offshore, closed-containment and extractive bio-remediation). An economic analysis of selected options then provided a comparison of financial performance and risk. The outputs of this initial component next informed strategic decision-making approaches; employing scenario analysis to explore plausible strategies for the adoption of land-based recirculating aquaculture systems; and qualitative modelling to understand the causal dynamics driving and regulating the industry, and their impact on technology selection. Whilst it was clear that business economic viability is paramount, the results suggested that societal acceptance (the Social License to operate) is playing an increasingly important role in influencing business decisions. There is no single ‘right' technological solution; social acceptance, in particular considerations regarding human wellbeing, trust, and animal welfare concerns, will shape the business environment and therefore technology selection. The research emphasised the importance of employing a balance of tactical and strategic decision-making techniques, and of engaging with a broad range of industry stakeholders. It also highlighted the complexity and dynamic nature of the industry and that key variances (economic, regional, strategic, technological, and temporal) must be included in decision-making.

This research investigated the relationship between several firm-controlled, marketing and management factors and firm performance. Hypotheses describing the relationship between the strategic, geographic, tactical, technological and organizational factors and firm performance of hardwood lumber manufacturers were tested. These factors were operationalized, measured in a mail survey and used in statistical analysis to identify relationships among the variables. An adjusted response rate of 19.8% was obtained from the mail survey. Non-response bias was not found to be a significant problem in the data. A twelve measure performance indicator was developed and utilized to evaluate the performance of hardwood lumber manufacturers who were predominantly privately-held companies. The averages for the profit and costs performance measures were the lowest of all twelve performance measures and this suggested that firms should focus improvement on these measures. The current marketing tactics, including species mix, product mix, customer mix, and promotion mix was determined. The utilization of advanced production technology has increased in the industry since it was last measured in 1999. The majority of respondents (60%) had dry kiln operations and 49% had a surfacing mill. Thirty five percent of respondents indicated that their company was certified by either forest, chain-of-custody, or both. Of the five firm-controlled factors investigated in this research, four of them were found to be related to firm performance. Geographic location was not found to be related to the performance of hardwood sawmills. Firms who were backward integrated and firms who were both backward integrated and forward integrated performed significantly better than firms who were not vertically integrated or forward integrated. Higher performance scores were associated with larger firms, firms who had multiple sawmills and firms who were members of the NHLA. There was no relationship found between diversification of the product mix, species mix, customer mix variables and performance. The diversification of a firm's promotion expenditures was positively correlated to performance. Firms that used optimized headrigs, optimized edgers and optimized trimmers performed significantly better than did firms not using all three of these technologies. Firms that used computer based log tallying, lumber tallying or inventory control performed significantly better than firms utilizing none of these technologies. An increase in the use of business strategy from previous studies along with a shift towards the use of a differentiation strategy was discovered. Firms interpreted to be following a hybrid differentiation/cost leadership strategy performed better than firms following a cost leadership, focus, or differentiation strategy. The implication of these results is that larger, vertically integrated firms are likely to perform better than smaller, non-integrated hardwood lumber manufacturers. It is recommended that firms diversify their use of promotion media and venues in order to attract new customers. Adoption of production and information technology will help some hardwood lumber manufacturers improve their performance. It is recommended that hardwood lumber manufacturers control costs and differentiate their products in order to gain competitive advantage. / Ph. D.

The thesis aims to examine how the formation of fa&ccedil / ades, that is, the interface with a dual response both to interior functioning and exterior urban fabric, is separated from the totality of architectural design by new technological developments and design intentions. This aim is accomplished in three sections, respectively: analysis of the fa&ccedil / ade, the properties and formation process in time / examining the fa&ccedil / ade formation of the high-rise office buildings in Levent-Maslak area in respect to the analysis and examining the working principles and marketing attitudes of fa&ccedil / ade manufacturing firms in terms of their role in fa&ccedil / ade formation. The focus is on the description of a fa&ccedil / ade and the process that generated the autonomy in time is examined. In this sense, the thesis analyzes that the &amp / #8216 / free-fa&ccedil / ade&amp / #8217 / application, by which physical autonomy is totally gained, transforms the fa&ccedil / ade to a production element by using the technological developments and specifications of curtain-wall system in the Turkish context, in particular in Levent-Maslak area. Besides the technical availability, the representational qualities of the new materials transform this production based character of the free-fa&ccedil / ade to a more representational character as an object-fa&ccedil / ade. Finally, the study investigates how the technical knowledge inherent in the new fa&ccedil / ade systems gives the authority,in formation process of fa&ccedil / ades, to the manufacturing firms instead of the architect. It is therefore stressed that the changing role of the architect in the formation process of fa&ccedil / ades is often based on the working principles and marketing attitudes of fa&ccedil / ade manufacturing firms at present.
